Description

Electric bicycle operating device

The invention relates to an electric bicycle operating device.

According to the previous, the traditional bicycles were fully stepped on by human power, driving the chainring to drive the chain to rotate, and the chain then driven the chainring of the rear wheel to rotate the rear wheel forward. In order to increase speed and save effort, the bicycle industry has combined the traditional chainring chain structure. Motors and electric bicycles began to appear, enabling electric bicycles to have both a variable speed function and a motor drive function to change the gear ratio of the chain engagement and motor drive to achieve a labor-saving riding effect, making it easier to ride.

However, when the user is changing the speed while the motor is still actuating, the chain will be subjected to the force of the motor and the tension will be too large, so it is easy to cause the chain to fail to smoothly switch the chainring or the chain breaks. The motor must be stopped first. (For example, let go of the throttle of the handle), the gear can be shifted to ensure a smooth shifting process. However, this process is too cumbersome and generally users often forget to stop the motor first to shift, which causes such problems to occur frequently. The shortcomings of improvement.

Therefore, it is necessary to provide a novel and progressive electric bicycle operating device to solve the above problems.

The main purpose of the present invention is to provide a bicycle operating device. When the rotating sleeve of the bicycle operating device rotates, it can have a sense of tripping for reference by the user. The user can thereby learn the range of rotation angle of the rotating sleeve, and the The signal transmitter is triggered to transmit the first electronic signal for functions such as powering off the motor or issuing a warning light.

To achieve the above object, the present invention provides an electric bicycle operating device, which includes a base, a rotating sleeve and a signal transmitter. The seat body is sleeved on a handle of an electric bicycle and defines an axial direction. The rotating sleeve is sleeved on the seat body so as to rotate along the axial direction. The signal transmitter can selectively transmit a first electronic signal. Wherein, one of the rotating sleeve and the seat body is provided with a plurality of grooves arranged along the circumferential direction, and the other is provided with an elastic resisting member, which normally radially biases against the one of the Groove. Wherein, when the rotating sleeve rotates relative to the base body, the signal transmitter is triggered to transmit the first electronic signal and the resilient member deforms to jump out of the groove and spring to another groove.

The following merely illustrates the possible implementation forms of the present invention with examples, but it is not intended to limit the scope of the invention to be protected, and will be described first.
